Class 375/377/387 Sound Mod

The Electrostars are one of the most iconic commuter rail platforms you can find in the UK - all electric, and quite standard trains. Many operators use them and they continue to serve the busiest regions of the network. As the Train Sim World franchise continues to grow with greater quantities of the same train, it's time to produce one mod which affects them all. The audio is as follows:


Plenty of inverter sounds

  • The new soundset has separate interior and exterior recordings mixed effectively
  • Sounds include the switch from the CPWM type to the SVPWM technique before synchronisation
  • Sync includes all harmonic audio, not only preserved, but as-recorded

Detailed gearbox audio

New running recordings

  • Audio sampled from 377419 has been mixed anew to the Electrostars
  • There's a 20% chanced that knackered wheel tread sounds will play at high speed
  • More running recordings are used with the new mix than before

Additional flange squeals

  • Several clips have been implemented for these trains at different speeds
  • These have all been recorded from 377419
  • At very slow speeds, sporadic scraping noises play
  • For moderate speeds, squeals become intense - a realistic volume level
  • Once the train travels faster, squeaks are more airy - like a grating sound
  • Subtle wheel flange noise can still be heard at high speeds

Dozens more track joint clips

  • 93 recorded Class 377 and Class 387 track joint sounds have been added
  • More violent volleys of clicks and clacks will start playing as the train travels faster over joints
  • Additional sounds have been mixed for the interior of the train

Clearer miscellaneous sounds

  • Extra recordings have been included to replace, squeaks, rattles, converters... etc
  • Where possible, dedicated recordings are provided for their respective trains such as horns, fan whirs, doors... etc

Affects the following trains

  • Southeastern Class 375/9 (Southeastern Highspeed) - SE Blue
  • Southeastern Class 375/9 (Southeastern Highspeed) - SE White & Grey
  • Southern Class 377/4 (Brighton Main Line)
  • Gatwick Express Class 387/2 (Brighton Main Line)

Known Issues

  • London Commuter for Train Sim World
  • Southeastern Highspeed for Train Sim World
  • Rail Operations Group BR Class 37/7 Add-On

would hope you got plans to do the pacer as well coming out soon as i hate the sound of it sounds like a 101

Avatar of ItsYa165

The issue is that they're basically all gone. But to be fair, the pacers have had a couple different engines and used to be all gearbox before hydrostatic

hey I have a question, could you at some time please make your fun soundmods compatible with TSW4? I really liked the different sound for the MAG 423, but now it's just the normal sound :(

I believe Linus Train Tips has started looking into the Train Sim World franchise now. Get in-touch with him about this proposal since he has real recordings of the train.

mate the recommended mod you put in does not actually work for tsw4 unfortunately, the files have not yet been updated to tsw4 but i believe its one of DTG's main things to to fix. at least thats what they said in the november roadmap.

Your mods are awesome, but after each update differently named, so I don't know which file to delete. Isn't better name it samely to prevent duplicating them?

Avatar of ItsYa165

This is definitely a you problem - it's not so good like this:

  • Not everyone follows the mod so it needs to be made really clear whether the file is different to their one
  • The changelog is based on the version I give to the file, I can't date it because nobody remembers dates
  • If a new version does not work, I need to be able to quickly backtrack to the one I know works and upload it

For you installing the file, just set the mod folder to alphabetical order. This way the old and new are always next to each other so you can clearly see what to delete... and if you need to find a mod, it is easy to find alphanumerically.

And besides... nobody said you can't just replace the existing file yourself. If you want to overwrite an old file to save 1 click and 1 key - do it. The file name does not affect the content of the mod and this would solve your problem.

Alright, I'll pick a different recording later. But it would be an SE 377 rather than from the actual SN 377

I test it between London and Brighton. Very good sound mod !
Is it possible for you to extend it for the Class 377 of East Costway Line ? Thanks in advance !

Avatar of ItsYa165

No. To heck with the East Coastway Class 377. Ask Alexendre L if they'll redo the mod which replaces it.

These are all excellent! The 375 is finally drivable after the last update!
Any chance the AWS green signal ping can be turned down a bit? It's really loud on both the 375 and 377. That's my only bit of feedback.
Thanks for all the work you do!

These are not modded but potentially

Avatar of FrankStevenson
FrankStevenson 5 days ago

Yeah that would be cool if it could.
Right now it's extremely loud and it bounces left and right in my headset. I think it definitely needs a tweak

Avatar of FrankStevenson

Also it's worth noting that the AWS ping is too loud by default without this mod installed. I'm just thinking you might have the know-how to adjust it. ;)
